Just recieved my new FICM that I bought off of ebay, but I do not know if I need to have it reprogrammed by Ford, or if I can plug it in now and it will be fine?powerstroke ficm : eBay Motors (item 300421958863 end time Apr-30-10 07:57:16 PDT)

If it was pulled from a running truck, it should just plug right in and fire up. If not, you will need to have it reprogrammed.

Are you having the low voltage DTC's on several cylinders? Is your truck turning over as fast as it ever has? If your batteries are weak, replace them both. Bad batteries are also bad for FICM's. You may need 2 new batteries and a new FICM. Possibly try the batteries first, and maybe get them tested individually.

I am getting new batteries today, and I hope that is it. Thanks for your help.

It was my battery cables. They were all corroded, dealer wants $300 plus for them. WTF!
